Replacing all the discs & jacking the car up...

Post by m4rcus »

Hi,

I'm going to be replacing the front and rear discs and pads next weekend and I've got a question as I'm thinking about jacking up the and putting it on axle stands front and rear and working on it whilst there are no wheels on it... so my question is... is this a stupid idea?

Cheers,

M

Just jack the rear up under the subframe, and then do each front individually. Easiest way imo, replacing pads/discs doesnt mean you have to get under the car, so just use the jack, no stand needed really.

Umm, imo you should always use axle stands, you should never rely on a jack alone!

m4rcus - no problem with raising the car entirely and removing all wheels, just make sure its got axle stands at the appropriate points.

unless youve got 4 mechanics workin on the car at the same time, why would you want to jack the whole car up? one man can only work one corner at a time so just jack up the corner you need. and use an axle stand on it, never relie on a jack to keep the car up. its not worth it. if you cant afford axle stands , at least put a wheel under you sill so if the car does come down it wont smash to the ground damaging your disks, limbs etc.

Thanks for the replies. I've got the axle stands so that's no problem. The one reason that I was thinking about this route is the bleeding of the brakes. I remember somewhere (prob on here) that someone would bleed all four brakes at the same time running 4x pipes into 4x jam jars half filled with brake fluid, so I thought I'd give it a go whilst they're all up in the air. If I can be ar$ed I might even paint the calipers.

@ tommy-c

Just to be on the safe side... can you clarify which are the best places to place axle stands when jscking the whole car up?

Cheers.

I know it's @ Tommy but I can answer this as I've just done the same work myself.

On your sills, at the front and rear you should see 2 small notches in the long metal strip under the still. Looks like this:

n__n_________________________n__n

Between those two notches is where you put the jack/axel stands.

Hope this helps dude :thumleft:

Cheers for the info, love the text explanation!

A further question regarding the jacking points you both describe... the car jack is designed to sit around the _n__n _ bit, but an axle stand just has \____/ for support, therefore meaning that the pressurewillbe applied to the n__n bit which is just several pieces of metal formed into a seam... would using subframe/chassis point be better?

The best way to raise the front is using a trolley jack on the spot shown on the third photo here:

www.mr2turbo.info/pics...rside.html

On the saddle of the jack use a 2"x4" piece of wood which straddles the width of the car slightly shorter than the width of the plastic undershields. I've also notched the timber so than it doesn't damage the shields which also makes it easier to get in place. When the car is raised place axle-stands under the ends of the timber and drop it onto these.

hi there

skipping past the jacking question I wanted to ask about bleeding (incidentially, I use a small block of wood over my trolley jack on the flat section of sill next to the notch - has worked great so far)

when replacing discs / pads, you don't need to touch the fluid (if you don't want to). you may need to syphon some out of the master cylinder, as the thicker pads will need the pistons pushing back into the caliper, thus pushing the level of fluid back up in the master cylinder.

I use a big kitchen baster for this - works a treat.

However, you do want to bleed the fluid, but why not just replace it all? It should be done every 2 years according to some service manuals, and from a fresh container. to stop air getting in you'd basically just pump more through when topping it up from your new bottle of fluid.

When I've bled brakes, I've always done them one wheel at a time, starting furthest away from the master cylinder and getting closer, ending at the drivers front wheel.

I did buy a halfords Ezebleed one person bleed kit, but it was pants - I just cut the one way valve off and put it in a jam jar with fluid in (tip: I put a big rock in the bottom of this jar to stop it getting knocked over by a curly tube).

2 people make bleeding a lot easier, but my pedal is rock hard by doing only 1 wheel at a time - 4 wheels at once would just mean your attention is split 4 ways IMO!
